How to Beat "Plague Inc." Neurax Worm on Normal

Ashleign is a woodworker and yard enthusiast. She can be found as enthusiast.mysticalnerdtv on Instagram and mysticalnerd on Twitch.


Neurax worm is a lot like Parasite. As a matter of fact, that's exactly what it is, except that this time we have a whole new set of rules, transmissions, symptoms, and even a new ability.

This is a big tutorial with big words, but if you're using the full mobile version with increased speed or Plague Inc. Evolved for the PC, this level should take no more than ten minutes.

Note: We will allow all symptoms to mutate.

Evolved Neurax Worm Walkthrough

Let's Get Started

If you're on your phone, be sure to swipe right to view the complete table.


1. Start your Neurax Worm in South Africa.



2. Build your DNA points to (25).

Concertina Locomotion, Undulatory Locomotion, Air 1, Water 1.


3. Build your DNA points to (25).


Cold Resistance 1, Trojan Planes, Drug Resistance 1.

4. Click on airplane bubble pop-up and infect islands first.



5. Build your DNA points to (33-35).

Water 2, Air 2.


6. Continue to use Trojan Plane Bubble to infect islands.



7. Build DNA points to (125).

Air 3, Eggs 1, Eggs 2, Water 3, Eggs 3.

Drug Resistance 2, Cold Resistance 2, Genetic Hardening 1.

8. Build DNA points to (100).


Genetic Hardening 2/Neural Breach, Cerebral Tendrils, Frontal Mesh, Immaturity, Mania.

9. Wait until everyone is infected (message will display).


Aggression, Acute Encephalitis, Cognitive Scrambling, Schizophrenia, Hallucinations, Blindness.

10. Spend your points as you choose. I prefer to use more lethal weapons at this point, but it is up to you.

Andrej on August 13, 2020:

Cure is compleated before infected goes to 100%

Tina on April 28, 2020:

There is no such thing as water 3 or air 3 only bio aerosol so I think you should pick it.

Shuu-chan desu on April 21, 2020:

Worked on the first try with 74% cure.

Have been having the issue of either killing the infected too slowly or too fast before everyone was infected. This was a real help, thanks!

Cheeeeeeeese on March 27, 2020:

The cure was WAY too fast and I didn’t stand a chance. :(

BannerBomb on March 23, 2020:

The video tutorials linked on this site don't follow the same steps and are much better to follow.

? on March 16, 2020:

It Didn't Work, I Didn't Even Get Close.

mew on February 21, 2020:

second time,thx

Baptiste on February 04, 2020:

Thank you, this walkthrough work in 699 days. This level and bio arme are a lot of fun to do :)

Loveyoulongtime on February 03, 2020:

Again on PC (Steam) this has worked like a charm.

Beat it in 928 days, 70% cure

I started off in Brazil tho and collected 100 DNA points and then followed the guide. Step 8 I waited until I had a lot of points and then did everything up to Hallucinations the same way but I did not have it in me to make them poor people blind, this was so mean Ashleign. Instead I went with OBSESSION, DEVOTION & ADORATION. This way the rest of humanity will die with a warm and fuzzy feeling on the way out. Going this route you will have to spend a few DNA points to stop development of the cure, I did it at 70% and research halted immediately.

TheRegularTerrarian on January 31, 2020:

To all those that want the Transcendence ending, make sure you infect half the world (play the game like normal), get Trojan Planes and Drug Resistance 1, then rush the symptoms to the Transcendence upgrade, then just sit back, keep upgrading, and wait.

Blyat Vadim on January 31, 2020:

You don't have any of the upgrades clearly labelled it was a lot of menu scrolling to figure out what was what...

Chrisie on December 12, 2019:

Worked great first time, 689 days, 51% cure

Luis. on November 09, 2019:

Bad. Didnt work for me. I want one that wins Transcedence achievement. Just got eradicated in 664 days and killed 1500 (a lot for Transcedence). Even with Extremophile, Genetic Mimic, Suppression, Metabolic Hijack and Translesion+, 664 days and one more eradication.

asentientplant on October 28, 2019:

Hey thanks! I started in India and eat it on the first try with this.

607 days, cure was @ 45%.

After Step 9 I like going into symptoms and getting the one that messes up language, and then Coma. Those really stop the cure!

my ass on June 15, 2019:

this has helped me a lot but yet I also got 97% cure XD

None on June 09, 2019:

1st time win. Very good strategy. 58% cure.

IdunnoMyName on May 22, 2019:

All people infected just when cure is complete. Didn't work AT ALL.

But hey, I'm still trying :)

Rose on April 26, 2019:

This is the only strategy that has gotten me to win. Thank you so much

ThisGuideIsBad on March 24, 2019:

Didnt even get to infect everybody.

ProXuS on March 14, 2019:

728 days and cure at 78% Thanks scientist guy :P

Adam on February 22, 2019:

Before everyone was infected the cure started curing every one, I did every thing it said to do everything!!

Someone on January 15, 2019:

I can't find Eggs 3!

BBPanda on December 21, 2018:

Followed to a T but the cure was developed while waiting on step 9. =(

Bg on December 15, 2018:

444 days 32% cure because on step 8 I went straight for trancedence

N/A on December 04, 2018:

Cure but I was on “Brutal”

Marcus Aure1ius on September 29, 2018:

Awesome! You have this game.down to a science. 703 days, 74% cure before everyone forgot what they were doing @ roughly 670 days and perished shortly thereafter. Excellent work!

jojo on September 18, 2018:

it worked for me finish in 784 days cure75% score of 9550 3 biohazard

Lucy on September 18, 2018:

Thank you thank you for this! Beat it in 709 days :)

PD-IX 42 on August 08, 2018:

This is good even i haven't killed all the world but i still won!

Chuck on June 21, 2018:

You went the wrong way. First attempt and I beat it in 462 days. You're playing this one wrong

N/A on January 11, 2018:

Lethality is the opposite direction you need to go you fool!!!

Harry on December 28, 2017:

Once I finished the tutorial, threw some of my own bits in. Finished with 45% finished cure.

chkn on December 08, 2017:

worked, the cure was 91% complete when i was done but i added a few more things at the end and i think without those i would've lost

Podzilla on November 18, 2017:

Thanks, the trojan planes helped a lot (ironically the islands got randomly infected, so I sent them to Canada since they take a while for infection) love the guide!

Ed on November 04, 2017:

Great guide, but I recommend anyone following this guide to disregard the final step. Once everyone is infected, evolve obsession, then devotion, then transcendence. This immediately wins you the game and also nets you the achivement ‘Assuming Direct Control’.

VortexIND on October 30, 2017:

690 days

Cure research around 80%

Wow, it really works on October 28, 2017:

It is really working all humanity extinct in 772 day and only 53% cure complete!

Lose one time because I didn't buy cold resist 2

Tim on October 19, 2017:

Did not work. Had to slow down the research as much as I could. but still, Greenland and Iceland survived.

Max on September 19, 2017:

Thanks so much! all of your tutorials have worked for me.

Jeff on September 13, 2017:

Finished in 777 days LOL

idk on August 26, 2017:

This worked just fine for me- I have no idea why people are saying it didn't work for them.

Yeah, sure Eggs 3 isn't a thing, but I honestly think that the people that complained about it and then "had it not work for them" didn't actually follow instructions at all.

If you follow instructions and then use the rest of the points, after absolutely everyone becomes infected, as you see fit (mainly towards symptoms and some towards drug resistant based abilities) you'll find that you'll succeed with around 600-800 days and 50-70% cure rate.

I replayed this mode 9 times following this guide to the letter and didn't fail once after following this guide.

There's no way that this guide isn't successful if you have it set to normal difficulty and nothing else. Anything else and it doesn't work- but it's not a guide on how to win on "brutal bacteria mode". It's a guide for "normal neurax worm". That's it.

Tsuskasa on July 26, 2017:

Thanks for the tutorial! Worked on the first try for me, there's something rather satisfying about watching those red dots slowly spread from country to country...

Penguin on June 20, 2017:

I love your tutorials. I had stopped playing this game because Fungal stuck me so hard... but your explanation has relit my love for this game. Thank you so much and I hope you keep doing what you're doing :)

kiki on June 11, 2017:

These tutorials are amazing!

Joe on June 07, 2017:

I was about to say this guide didn't work and it needed to be changed slightly because I came within hundreds of people of winning in five attempts, then I found I left it on brutal difficulty, won first time after I put it on normal again XD thank you

orteam on May 28, 2017:


71% cure 729 days

Frustrated Gamer on May 23, 2017:

I've tried this twice and I've lost both times following this to a T! Plus, "eggs 3" isn't even a thing. This walkthrough is useless and disappointing since most on here are accurate. Llease rework your strategy into one that actually works please.

Bmaximum on April 19, 2017:

Hey, had plague for a while and wasn't able to make progress past bacteria, the cure would just progress too fast. With help from your guides I've been able to breeze through the game and have fun. I know this is a few years late but thank you

Anonymoustache on March 06, 2017:

I enslaved humanity with only 100,000 or so people left!

MTG K1809o on February 28, 2017:

In the part where you first evolve symptoms it's better if Chris the path were you enslave humanity

Tony B. on February 28, 2017:

You have been a great help, thank you.*****

Suwako_NKM on February 09, 2017:

Works perfectly on brutal for me thanks a lot for the guide

Rainwing on January 21, 2017:

I recommend updating this because it didn't work for me and I followed the instructions perfectly.

Jen Anderson on January 03, 2017:

810 days 75% cure

I followed the instructions exactly as they're written and had no problems on my first try. Thanks!

Some guy on December 27, 2016:

Doesn't work. I tried it three times and it didn't work.

IdjitKicker on December 26, 2016:

No, did not work, followed exactly and ended up with 95% researched before got message that 100% infeceted. Maybe bad luck, will try again.

RandoM UseR on December 22, 2016:

Nope didnt work for me - Ill try again.

Nash presto on December 16, 2016:

It only took me 580 days and 76 cure. Thanks for all the help:)

Rozack on November 04, 2016:

Andrethebruh on February 16, 2016:

Worked at first try! :D killed them all,64% cure (used reshuffle 3 with the rest of the points) and 713 days :3

Awai on February 08, 2016:

Sans on February 07, 2016:

FireMaker112 on December 29, 2015:

For some reason, it never works for me. Tried 14 times.

Chadhulhu on October 25, 2015:

good ideas.

Nike on October 18, 2015:

Thanks you I finally got past it!! You my friend are amazing!!

Zute on September 20, 2015:

Followed your guide step by step a few times over. Still managed to lose on this level. Which makes me sad because your guide is very thorough. Going to keep at it though.

Jrye on September 20, 2015:

Awesome i think you're awesome man

Mila on August 30, 2015:

Thanks to you im able to pass levels. Thank you Ashleign :)

Matanel on June 25, 2015:

Thx! You should get genetic hardening 1 & 2 and genetic reshuffle 3 because until I got genetic reshuffle 3 the cure got up to 97%!! But otherwise, this was very useful. Also, your other guides are awesome until prion. Still can't find a way to get past that one! But still, thanks for all the other guides!!

Lance on June 21, 2015:

I personally prefer to go the non-lethal route. Once everybody's infected, I shoot straight for Transcendence. I name my Neurax Worm Cthulhu, so the game ends with everybody worshiping Cthulhu.

AmyP on June 16, 2015:

yes, you can win using transcendence. i had 150 DNA points and only 48% cure for 3 Biohazard/Stars. I followed your tutorial except I transcended.

Christian on March 28, 2015:

Thanks so much for the tutorials they help me so much!

You are awesome!

Mark on March 14, 2015:

Wow, works great! Thank you so much! Those scientists don't stand a chance against this walkthrough.

Snuffs on March 09, 2015:

So, thank you yet again for a great guide.

This one was a bit nervwracking. The cure got up to 99% for me. But that was due to me being sloppy and not paying well enough attention to my points. But i manged to rewrite my strain ( required all 3) And managed to kill everyone off before the cure was done. Stopped at 87%.

And again, Thank you for the guide. You're awesome!

Guest on December 24, 2014:

I've followed this to the tee over five times and nothing seems to be working.

Nigel Kirk from Calgary, AB, CAN on December 02, 2014:

Thanks for posting these tutorials. I write on anime a lot here, so obviously I'm a bit of a nerd, and what nerd doesn't love gaming? Especially with a science aspect. I just picked this game up a few days ago. I do try each plague without tutorials first, but every now and then I get stuck. Thanks a bunch!

Ashleign (author) on November 18, 2014:

To be honest I have tried doing tutorials for the brutal ones. They just aren't popular enough to keep doing. I have other tutorials on my youtube you might find funny as well. I've come a long way from a guy uploading raw video to youtube lol.

nick on November 18, 2014:

These tutorials have worked Every Single time, and the commentary is pretty funny. Id like to see some Brutal walkthroughs as well!

shaddurak on November 06, 2014:

great guide but i assumed direct control and enslaved with transcedance and got a steam acheiv =)

Luitzifa on November 02, 2014:

World in Slavery after 408 Days. 16% Cure, Score 40280

Mordyr on October 30, 2014:

Beat it in 514 days using transcendence

Steel Hyaena on October 21, 2014:

Third try via this tutorial, folowing all your tips... not working for me.

AeroAviation on August 15, 2014:

I did this but with a slightly different approach after everyone was infected, I made everyone worship it and turned them insane so yeah... they are enslaved now

NitroQueen on August 11, 2014:

Worked like a charm on 1st try..thanks for the great tutorial :)

My Toxicosis worm killed all in 881 days

Cure at 61% complete.

asd on July 27, 2014:

there's no air and water in the new version

Mortalich on June 30, 2014:

Thank you !

Ashleign (author) on June 27, 2014:

glad to hear it!

][)enys on June 27, 2014:

All of these so far have been awesome and working on the first try for me. Thanks a lot :D

Ashleign (author) on June 27, 2014:

Nice. Well thank you for that. I'll look at changing the tutorial.

BillTheBard on June 26, 2014:

Just a quick note -you can win quicker by not going for the lethal symptoms, but instead going for the Transcendence ability - once everyone is infected, they don't start dying, they start worshipping the Worm as God! Instant Victory!
